An Implementation of Cognitive Resource Management on LTE Platform

Executive Summary

In this paper, the authors describe an LTE based demonstrator of the Universal Link Layer API (ULLA) and Cognitive Resource Manager (CRM) modules that are developed in ARAGORN project. The demonstrated LTE system comprises one LTE TDD eNode B and one User Equipment (UE). They first introduce ULLA and CRM framework and then demonstrate their suitability to be implemented with the existing LTE equipment. They show how, through ULLA, CRM is able to obtain PHY/MAC status information of the link between the eNode B and UE, and in turn change system parameters to achieve better resource utilization and transmission efficiency. The control logic can be implemented with simple adaptation or policy-based intelligent methods.
